BOTTLE-STOPPER.

Specication of Letters Patent.

Patented May 26, 1914.

Application led .Tune 9, 1913. Serial No. 772,494.

i adapted to be employed in the neck of a bottle, and is so constructed that the contents of the bottle may be readily poured therefrom, and in attempts to refill the bottle by force, either positive or negative, that is, by a positive pressure or a vacuum, or by shaking the bott-le, devices normally inoperative are actuated and moved to position to permanently close a port at the inner end of the stopper, making it then impossible to either introduce liquid into the bottle through the stopper or to pour out whatever liquid there may have been forced in the bott-le before the said devices operate, as will be hereinafter more particularly described.

In the drawing, Figure 1 is a central longitudinal cross section of a stopper illustrating my present invent-ion. Fig. 2 isa cross section on line m, Fig. 1. Fig. 3 is a cross section on line g/ y, Fig. 1. Fig. 4 is across section on line a z, Fig. 1. Fig. 5 isa central longitudinal cross section of a modified form of my invention. Fig. 6 is a cross section on line m tudinal cross section of a further modification of the invention, and Fig. 8 is across section on line Fig. 7.

Referring to the drawing, larly to 1 to 4, inclusive, my improved stopper preferably comprises a body member made of glass or any other suitable material, and is adapted to fit within and be secured in place in the upper part ofthe neck of the bottle. The body member of the stopper 1s indicated at 10, and at its outer end is provided with a mouth 11. At an appreciable distance from the outer end of the stopper is a transverse wall 12, preferably made integral therewith, and in the outer surface of the body of the stopper immediately at one side of the transverse wall 12, is a circumferential recess 13. Extending from the base of this recess, through the body of the stopper, and into the bore provided therein, are recesses or ports 14. Similarly in the outer surface of the body of the stopper, and 1mmediately beneath the transverse wall 12, is a circumferential recess 15, and from the and particu- Fig. 5. Fig. 7 is a central longibase of the recess and extending through the wall of the stopper are p orts 16. In that portion of the outer between the circumferential recesses 13 and 1 5, a series of recesses or ports 17 areprov1ded, these ports 17 being preferably staggered in relationship to the ports 14 and 16, so that it is substantially impossible to tamper 1n any manner with those parts of the stopper situated within the transverse wall 12.. The inner end of the stopper, or that portion thereof beneath the transverse wall 12, when the stopper is in position, is provided with a cylindrical bore, i'n which I employ a movable member 19. In its outer sursurface of the stopper,-

face, this movable member is provided with a series of longitudinal ribs 20, providing intermediate spaces or passage-ways 21, and in its upper surface, this movable member is also provided with recesses preferably semicircular, as indicated at 22. Extending across the upper or outer end of the movable member 19 is a cross bar 23,-which is provided with a pin 24. Within the movable member 19, I employ a stopper 25, made of cork or any other suitable material, and adapted to normally lit and be maintained within the movable member 19 so as to move therewith in both directions, either by means of the pin 24 entering the stopper 25, or by there being sufiicient friction between the outer surface of the stopper and the inner walls of the movable member to maintain the stopper in position therein against accidental displacement. Between the transverse wall 12 and the outer end of the movable member19, I employ a controller 26. This is preferably semi-spherical and is provided with a. 'series' of ports 27. This-controller 26 is so placed within the stopper that its curved surface normally contacts with the outer end o-f the movable member 19, and as will be understood, has a tendency, when the bottle is tilted, to force the movable member to its normal position. Suitably secured to the inner end of the stopper, is a member 28 having a discharge port 29 therein, and provided with a. seat 30, and also with a seat 31. In their normal positions, the movable member 19 rests against the seat 31 and thecontroller rests against the upper surface of the movable member in contact with the cross bar 23.

In tilting the bottle, which is represented at a, to pour the contents therefrom, the movable parts will assume the position shown in F ig. 7, and the liquid can readily flow through the port 29, through the passages in the periphery of the movable member, either through the port 27 and the controller 26 or around the same, and through the ports 16 and the recesses 15, through the recesses 17 and the recess 13, and thence through the ports 14: to the mouth of the stopper. If, in emptying the bottle, its entire contents are not poured out at one time, a portion of the liquid will remain in the stopper between the movable member and the upper or outer end thereof. The pressure, however, caused by the weight of any such liquid, which may remain within the stopper is not suiiicient to disconnect the member 20 from the movable member 19, and inasmuch as, when the bottle is righted, the movable member seats against the valve seat 31', this liquid so entrapped will not be returned to the interior of the bottle but will remain within the stopper structure.

In practical attempts to refill the bottles, in which bottle stoppers are employed, it is customary to employ considerablylgreater pressure than that which could be exerted by the liquid contained within the stopper between the movable member and the upper end thereof, and this abnormal force whether it be pressure or the action caused by a vacuum, will dislodge the stopper 25 from its position in the movable member and force the same into the member 28 and against the seat 30 therein, which, as will be readily understood, will not only prevent the refilling of the bottle but will also make it impossible to empty any liquid which may have been forced into the bottle previously to this action of the stopper 25 taking place.

Referring to Figs. 5 and 6, it will be seen that I may employ a flange 32, adjacent the outer end of the stopper and adapted to contact with the end of the neck of the bottle therein, and also that the inner face of the stopper beneath the transverse wall 12 may be inclined or tapered, as indicated at 33, and provided with spaced longitudinal ribs 311 with the intervening .passages 35, in which instance the outer surface of the movable member 37 is also tapered, as indicated at 36, and the surface is plain or smooth, the

passages for the liquid being provided as hereinbefore stated in the inner surface of the body of the stopper. In this construction, I may employ a controller, which is bell shaped in elevation, and adapted to pass through the open outer end of the movable member and to contact directly with the stopper 25 so that in attempts to refill the bottle by shaking the same, the bell shaped controller member 38 dislodges the stopper from its normal position and sets it within the inner end member 28.

'Ihe modied form of the invention shown in Figs. 7 and 8 is similar in all respects to that shown in Figs. 1 to 4:, inclusive, with the exception that the walls of the stopper may be slotted, as indicated at 39 to provide passages for the liquid in emptying the bottle.

It is to be observed that in all forms of the invention the inner diameter of the movable member is greater at its inner end than on other parts thereof, providing for a shoulder 40, against which the stopper 25, after being dislodged from its position in the movable member, may strike and so be prevented from returning to its place in the movable member.

I claim as my invention:

1. In a bottle stopper, a casing having a discharge port and being adapted to t the neck of a bottle, a movable member having a port therein, and a device normally lying in the port in the movable member and which device is disconnected from the movable member and permanently lodged in the said discharge port by abnormal force employed in attempts to refill the bottle.

2. In a bottle stopper, a casing, a member within the said casing, and a device normally connected to the said member so as to permit the contents of the bottle to be poured therefrom, and which device, by abnormal force employed in attempts to refill the bottle, is disconnected from the said member and permanently lodged in a discharge port.

Signed by me this 5th day of June, 1913.
